AI Technical Summary

Benefits of technology

The patent describes an adapter assembly for a circular stapler that includes a tubular housing, a trocar assembly, and a camming member. The camming member is movable between a locked position and an unlocked position to lock or unlock the trocar assembly with the tubular housing. The adapter assembly also includes a button and a release button that can be actuated to move the camming member. The technical effect of this invention is to provide a more secure and easy-to-use adapter assembly for a circular stapler.

Problems solved by technology

As such, these end effectors are not compatible with surgical devices and / or handle assemblies that use a rotary driving force.

Abstract

A surgical system includes an adapter assembly and a tip protector. The adapter assembly includes a tubular housing, and a trocar assembly selectively receivable in the tubular housing. The tip protector includes a housing defining a channel therethrough configured for receipt of the trocar member, a first locking member movably coupled to the housing and configured to selectively engage the trocar member to lock the tip protector to the trocar member, and a second locking member movably coupled to the housing and configured to selectively engage a distal end portion of the tubular housing to lock the tip protector to the tubular housing.

Description

BACKGROUND1. Technical Field[0001]The disclosure relates to surgical devices. More specifically, the disclosure relates to handheld electromechanical circular stapling instruments for performing end-to-end anastomosis procedures.2. Background of Related Art[0002]Circular clamping, cutting and stapling devices may be employed in a surgical procedure to reattach colon portions that were previously transected, or to conduct similar procedures. Conventional circular clamping, cutting, and stapling devices include a pistol or linear grip-styled structure having an elongated shaft extending therefrom and a loading unit portion. The loading unit portion includes an end effector having a staple cartridge housing a plurality of staples supported on the distal end of the elongated shaft and an anvil assembly supported adjacent to the staple cartridge. During the surgical procedure, a physician may insert the loading unit portion of the circular stapling device into a rectum of a patient and m...
